The Raleigh area enjoyed a brilliant cloud-free sunrise today, seen in the first image at mid-twilight (better large on black) and above at sunrise proper (also better "http://bighugelabs.com/onblack.php?id=4236445207&size=large")... Although scattering had increased by sunrise proper, muting the colors higher in the sky, the dry air helped preserve much of the intensity of twilight's colors at the horizon. Sweet!
